Influence of structural and operating factors on mixing transfer of rotary energy recovery device through CFD simulation

The rotary energy recovery device (RERD) is an essential component in seawater desalination for decreasing the consumption of reverse osmosis plants. To research complex flow fields and mixing motion ducts a device, 3D numerical simulation was studied this work. Three-dimensional vortex structures were visualized identified based on Q criterion. effects operating condition structure parameter had been discussed. Simulation results indicated that interaction between vortices zone duct entrance led to high level turbulence intensity degree. process could be controlled by parameter. This paper provides new approach researching structural factors device.
